Dr. English is a family physician with more than 20 years in clinical practice. She earned her MD and completed her residency at the University of Toronto and is certified by the College of Family Physicians of Canada.

Her work spans women's health and mental health, and her care philosophy is simple: control what you can control. At Tide Health and Performance she provides medical governance and oversight for the Nurse Practitioner-led program.

Stacey is a CanFitPro Certified Personal Trainer whose relationship with fitness started in her teens and never let go, evolving from a passion for heavy lifting into a deep curiosity about how the body adapts to training and food, and rebuilds after being pushed to its limits.

She has tested that firsthand, coming back from a torn Achilles and a full hamstring avulsion and using emerging recovery tools to manage chronic inflammation. That blend of lived experience and relentless self-experimentation defines her coaching, which sits at the intersection of strength training, body recomposition and supporting clients navigating their journey on GLP-1 protocols.

Michael is a PhD scientist, whose academic research began in diseases of the brain, but his work today is shaped as much by lived experience as by the lab. A few years ago he was sedentary; today he trains for and races Half Ironman events, and he uses Mounjaro to manage his diabetes along the way.

That transformation reshaped how he thinks about health: the body is remarkably adaptable, and lasting change comes from working with our biology rather than against it. He writes and speaks on the intersection of GLP-1 therapies, fitness and training, translating complex science into clear, evidence-based guidance, with a particular focus on women's metabolic health. His goal is simple: cut through the noise and help people make informed, biologically grounded decisions about their health.
